title = "A novel design of a high performance passive millimeter-wave imager for security",
abstract = "This paper describes a high performance of opto-mechanically scanned millimeter-wave imager for airport security. It employs a crank-rocker mechanism to generate a high speed line scanning, which produces a horizontal FOV (field of view) of 30°. Accompanied by a frame scanning mirror of ±18° in the vertical direction, it brings about a two-dimensional scan of the scene of 146cmx75cm which is 1 meter away from the system. By this scanning mechanism, we use a single channel of a 94GHz receiver to collect the radiation from a convex lens which acts as the focusing element. Then the output of the receiver is passed to an A/D converter and is displayed on a conventional PC. The new scanning arrangement meets these requirements and has been being developed into a high performance, low-cost, and compact prototype system which hopefully will meet the present and future needs for millimeter-wave and terahertz imaging.",
